Frequently Asked Questions
Break each service type into separate line items with its own quantity, rate, and subtotal. For example, list exterior windows, interior windows, frame cleaning, and track maintenance as distinct rows. This clarity helps clients understand exactly what they're paying for and makes itemization transparent for both residential and commercial accounts. It also simplifies job costing and helps you track which services are most profitable.
Calculate your GST-inclusive price by multiplying your subtotal by 1.15 (adding 15% GST). Display the subtotal, GST amount (at 15%), and final total separately on the invoice. You must be registered with IRD to charge GST. Always show the GST component explicitly so clients understand the tax component, and keep records for GST returns. Ensure your invoice template clearly labels 'GST (15%)' to maintain compliance.
Yes, charging separately is standard practice because interior cleaning typically requires more time indoors and uses different equipment than exterior work. Most NZ window cleaners charge lower rates for interior services than exterior work. Itemizing both allows clients to choose services independently and gives you flexibility—some clients may only want exteriors or maintenance cleans. Transparency also builds trust with commercial property managers.
Absolutely. You can include gutter cleaning, pressure washing, frame repairs, or any related services as separate line items on the same invoice. This is common in NZ where clients often request multiple exterior maintenance tasks during a visit. Itemize each service with its own description, quantity, and rate so clients see the full scope of work. This approach improves cash flow by consolidating payment and saves you time creating multiple invoices.
Residential clients typically pay on completion (due on receipt), while commercial property managers often expect 7–14 day terms. Consider requiring a deposit for large residential contracts or seasonal services. For ongoing commercial accounts, 7-day terms are common in NZ and improve your cash flow. Always specify payment terms clearly on the invoice to avoid confusion. Faster payment terms reduce bad debts and administrative follow-up.
Include your business name and IRD number (if GST-registered), invoice number and date, client's name and address, detailed description of services, quantity, unit rate, subtotal, GST amount (at 15%), and total amount due. Include payment due date and your preferred payment method. IRD requires these details for GST compliance and audit trails. Missing information can cause disputes and delays with commercial clients who need proper documentation.
Create a deposit invoice showing the percentage or amount retained, clearly marked as 'Deposit' or 'Retainer.' When the final invoice is issued, reference the deposit and show it as a credit toward the total. For example: Final Total $575 – Deposit Paid $150 = Amount Due $425. This maintains clarity for clients and protects your cash flow. Always retain both invoices for GST and accounting purposes.
Use consistent invoice numbering and reference the contract or agreement date. For recurring services, create individual invoices for each visit with descriptions like 'Monthly exterior window clean – July 2026.' Include a contract reference number if available. For ongoing contracts, maintain a summary with all visit dates and amounts. This approach helps clients track their service history, simplifies your accounting, and makes quarterly GST returns straightforward.
